    What is the rate limiting step in aldol condensation of benzaldehydes with acetophenones?
    We now conclude that the rate-limiting step in the base-catalyzed aldol condensation of benzaldehydes with acetophenones, to produce chalcones, is the final loss of hydroxide and formation of the C═C bond.

    What is the rate limiting step in aldol condensation of benzaldehydes with acetophenones?
     
  1. Acetophenone and benzaldehyde can react to form benzylideneacetophenone (chalcone) in presence of ethanol and NaOH1. The reaction between benzaldehyde and acetophenone undergoes cross aldol condensation in presence of dil. NaOH23. In this reaction, benzaldehyde has no alpha hydrogen but acetophenone has alpha hydrogen so it undergoes aldol condensation to form β-hydroxy ketone2. Benzaldehyde can also be oxidized in the presence of potassium permanganate and sulphuric acid to form benzoic acid, which further reacts with sodium hydroxide to produce sodium salt of benzoic acid that is sodium benzoate4.

    What happens when Benzaldehyde reacts with acetophenone?
    The reaction between benzaldehyde and acetophenone undergo cross aldol condensation in presence of dil. NaOH. In this reaction benzaldehyde have no alpha hydrogen but acetophenone have alpha hydrogen so its undergo aldol condensation form β-hydroxy ketone. Furthermore, dehydration leads to the formation of the α, β – unsaturated ketone.

    Why do benzaldehyde and acetophenone undergo cross aldol condensation?
    Furthermore, dehydration of the initial condensation product is rapid which leads to the formation of the α, β – unsaturated ketone and prevents the retro-aldol reaction from taking place.
